Tested at Newbsanity: Altra Superior 4.0 is great for Obstacle Course Racing
The Superior 4.0 was a great trail shoe to try on this obstacle course, especially when things got slippery. It had plenty of grip with Altra’s MaxTrac Rubber & TrailClaw design. Altra Running’s Superior 4.0 also has a 21mm stack height to provide cushioning for the impacts an OCR participant may encounter. With Altra’s Footshape Toe Box and Zero Drop platform design, the Superior 4.0 is the Superior pick for someone looking to participate in Obstacle Course Racing.
